Fix bug report template

• Fix sudo password prompt not visible

  When using sudo in the subshells of the command substitutions in the heredoc, the password prompt is not visible, so the command seems to hang, while actually it's waiting for the user to input their password.

  To work around that, use sudo -v before the heredoc, so that the user's credentials are cached and sudo doesn't ask for them again (assuming that credential caching hasn't been disabled).

• Use journalctl with sudo

  Non-privileged users are not allowed to read journal messages from system services such as authd.
